What is RC522?

The RC522 is a popular radio-frequency identification (RFID) module used for contactless communication. It operates on the 13.56 MHz frequency and can read and write RFID tags. The module communicates with a microcontroller through a serial interface like SPI (Serial Peripheral Interface) and is often used in conjunction with Arduino and other development boards for RFID-based projects.

  • SDA (Serial Data Line):

Used for serial communication with the microcontroller (e.g., Arduino).

  • SCK (Serial Clock Line):

Clock signal for synchronization during data transmission.

  • MOSI (Master Out Slave In):

Data output from the microcontroller to the RC522 module.

  • MISO (Master In Slave Out):

Data input from the RC522 module to the microcontroller.

  • IRQ (Interrupt Request):

Optional pin used to signal the microcontroller about events or data availability.

  • GND (Ground):

Connection for the ground terminal.

  • RST (Reset):

Reset pin for the RC522 module.

  • 3V or 5V (Voltage Input):

Power supply pin, typically requiring either 3.3 volts or 5 volts, depending on the module version.
